Also known as L-ascorbic acid, THD ascorbate, ascorbyl glucoside, sodium ascorbyl phosphate
What is vitamin C?
Vitamin C is an antioxidant that protects your skin from sun and pollution damage, fades dark spots, and helps build collagen. L-ascorbic acid is the pure form with the most research, and it works best at 10% to 20%. Derivatives like THD ascorbate are gentler and more stable, which suits sensitive skin.

Vitamin C FAQs
Apply it in the morning on clean skin, before moisturizer and sunscreen. It boosts your sun protection.
L-ascorbic acid is the most proven form. Pick a derivative like THD ascorbate if pure vitamin C stings your skin.
Use vitamin C in the morning and retinol at night. That gives you both without the irritation.
A serum that has turned dark orange or brown has oxidized and lost strength. Store it capped, away from heat and light.
